Hundreds of people campaigning for Islamic rule in Bangladesh have clashed with police over a new policy advocating more rights for women.

Police used teargas and batons to break up the protests after members of the Islamic Constitution Movement (ICM) threw rocks in the capital, Dhaka.

Mokarram Hossain of Dhaka Metropolitan Police said there were more than 500 protesters and dozens were hurt.

Protesters had ignored a ban on such gatherings under a state of emergency.

It was imposed by an army-backed interim administration which took power in January last year.
